Assessing the success of conservation translocation establishment: Post‐translocation demography of Nubian giraffe (Giraffa camelopardalis camelopardalis) in Uganda

Conservation Science and Practice
Conservation translocations are increasingly important for restoring and augmenting wild populations of extirpated species or those diminishing rapidly.

Evaluating camera survey methods for estimating wild turkey abundance

Wildlife Society Bulletin
Accurately estimating population parameters rests on methodological approaches that provide unbiased, cost‐effective estimates; however, assessing accuracy of estimates can be vexing as true abundance is rarely known.

Demography and Behaviour of Teinopodagrion oscillans (Odonata: Megapodagrionidae) in a Protected Area of the Colombian Andean Region

Insects
The demography and behaviour of Teinopodagrion oscillans was studied in a protected area in the Andean region of Colombia. Adult damselflies were individually marked, and using their recapture histories, we estimated survival, longevity, sex ratio, and ...

Correcting random effect distributions to account for survivorship bias in individual heterogeneity Cormack–Jolly–Seber models

Biometrics
Abstract Survivorship (or selection) bias arises within statistical analyses where the observed data are subject to some underlying selection process prior to entry into the sampled data. For example, within capture–recapture studies, a primary selection mechanism is the survival until initial capture time.
